"The patent describes a system for evacuating individuals from a high level to a lower level using a rescue sleeve. The system includes a sleeve made of cloth or similar material, reinforcing rings, an extendible axle member, elongated spacers, and means for rotating the sleeve around the axle member. The method involves suspending the sleeve between two supports, providing an axle member between the supports, and using distancing means between the sleeve and the axle member. The technical effect of this invention is a more efficient and effective means of evacuating individuals in crisis situations."
Problems solved by technology
This feature presents a certain disadvantage in that the anchoring point of the lower end of the sleeve has to be placed at a distance from the building, depending on the height of the story designated as the evacuation point.
This operational pre-requisite may not always be satisfied, depending on the urban surrounding of the building in question.
Although the spiral sleeve concept and principles of construction adequately solved the above mentioned problem, certain aspects thereof needed refinement.

Embodiment Construction
[0026] As seen in FIG. 1, building 10 is on fire or under other disastrous situation calling for quick mass evacuation.
[0027] A retractable storage compartment 12, housing a rescue system, has been withdrawn from one of the elevated stories. The rescue system, presented in its final, operative position, comprises a rescue sleeve assembly 14 coiling down from the floor of the compartment 12 to a base plate 16 that has been lowered by cables 18 and 20 to the ground level (or to a lower story of the building, as determined by the operating rescue team).
[0028] The sleeve denoted 22 is made of canvas, preferably fireproof, reinforced by numerous rings 24 attached uniformly around the sleeve all along, at an equal distance one from the other for a reason that will be explained below. Although the rings 24 are shown as discrete components, it should be noted that instead of a continuous coil of flexible wire, e.g. of steel, may equally be employed, and the term “rings” as herein used is ...

A system for the evacuation of individuals from a first, elevated level to a second, lower level by gliding down a rescue sleeve. The system comprises a sleeve (22) made of cloth or the like material having an entrance end located at the first level and an exit end located at the second level. A series of equidistanced rigid reinforcing rings (24) embrace the sleeve (22). Elongated spacers (28) are provided, fastened at one end thereof to one of the rings (24) and at their other end to a centrally extending cable (26). One end of the sleeve (22) is rotated relative to the other end about the cable (26) so that the sleeve becomes coiled around it at a distance defined by the elongated spacers (28).
Description
BACKGROUND OF THE INVENTION [0001] The present invention relates to rescue systems for evacuating individuals trapped in high rise buildings in case of emergency situations such as fire or earthquake. [0002] The invention particularly concerns rescue systems of the kind disclosed in the inventor's International Patent Application, published Aug. 30, 2001, as WO 01 / 62138 (herein referred to “the WO Patent”). [0003] As described and claimed in the WO Patent, a system is provided for the evacuation of individuals trapped in multiple story buildings by gliding down a rescue sleeve. The sleeve is composed of sections, each section being made of a sheet material reinforced by a circumferential rigid support member, and the sections are connected to each other to form a continuous envelope. At least a pair of cables is provided, threaded along the sleeve, one at the bottom and one at the top generatrix thereof. A pair of winch systems are provided for winding the cables into a dedicated lo...
